A general reduction in UK energy production is an encouraging sign in the context of concern over the environmental effects of carbon dioxide production. The UK has reached peak point of indigenous energy resources utilisation and within the foreseeable future will become a net importer rather than exporter of energy sources unless Government policy permits expansion in nuclear power generating capacity. As North Sea oil and gas runs out, the UK will have to import 80% of its energy requirements from countries such as Algeria and Iran. It is legitimate to question the security of supply, the risk of being held to ransom and the strategic economic consequences.
